Bonds
What is an Ionic Bond?
An Ionic Bond is the force that holds positive and negative ions together.
What part of the cycle is our sun in right now?
Main Sequence.
What was the size of the Big Bang when it started?
About the size of an atom.
List 1 example of renewable energy.
Solar Energy.
What is a group and what does it tell us?
It is columns of elements and it states the number of outer electrons an element has.
What is a covalent Bond?
A covalent Bond is an attraction between atoms when they share electrons.
What way is our sun gonna go after it’s done with the main sequence.
Next to the planetary nebula (smaller way).
Within 100 seconds how big was it.
The size of our solar system.
What is 1 negative about Non Renewable Resources?
They have a limited supply.
What is a period and what does it tell us?
It is Rows of elements and it states how many energy levels an element has.
What is the difference between Ionic and Covalent bonds?
In an Ionic Bond electrons are transferred whereas in a covalent Bond electrons are shared.
What star characteristic determines a stars life cycle path?
It’s mass/size.
What is the Big Bang Theory?
States that the universe began in a enormously hot and dense state about 13.7 billion years ago.
What is the difference between kinetic and potential energy and give 1 example of each.
Kinetic energy is energy in motion 1 example of kinetic is a person jumping. Potential energy is energy that is built up and stored ready to be released 1 example is a quarterback about to throw a football.
What are some characteristics of metals and where is it located on the Periodic Table?
Metal has high shine, good conductor, and easily loses electrons. It is located on the left side of the Periodic Table.
How are you supposed to know how many dots to draw around an element for the Lewis Dot Structure?
You look at how many outer electrons it has.
Define fusion and fission and give 1 example of each.
Fusion is when atoms combine. This is what happens in the sun. Fission is when atoms split apart giving off energy. Fission is what they use for bombs.
What is Cosmic Microwave Background Radiation?
CMB is the result of the expanding and cooling of the Big Bang.
What is the first law of thermodynamics?
It states that energy cannot be created or destroyed it can only be transferred.
What are some characteristics of Noble Gases and where is it located on the Periodic Table?
Noble Gases already have a full outer shell (8) so it will never gain or lose electrons. It is located on the very right on the Periodic Table.
What element can be stable with only 2 electrons and why?
Hydrogen atoms because it only has 1 energy level which holds just 2 electrons.
What do the largest stars end up being?
Either a Neutron Star or a Black Hole.
How does Hubble’s Law support the Big Bang Theory?
It supports it because all galaxies show red shift, and are all moving away from Earth proving our expanding universe.
What is the second law of thermodynamics?
Each time energy is transferred it becomes less and less useful.
How do you determine the number of each particle: Proton, Neutron and Electron?
The atomic number tells you the amount of Protons. The number of Protons will always be the same to the number of Electrons. You take the isotope number and subtract it by the number of Protons to find how many neutrons it has.
